角度量块 Angle Gage Blocks角度量块 (JB/T3325)角度量块是一种角度计量的基准量具，用于检定万能角度尺，角度样板等。与附件组合，(利用测角边缘的小孔)，可用于检查零件的内、外角或精密机床加工中的角度调整等。角度量块分 I 型 (有一个工作角) 和 II 型 (有四个工作角)。0 级精度的工作角偏差不超过 ±3 秒，1 级精度的工作角偏差不超过 ±10 秒，2 级精度的工作偏差不超过 ±30 秒。订货时请注明名称，套块数精度级别，套别:例角度量块 7 块 0 级

Angle Gage BLocks (JB/T 3325)The angle gage blocks are a standard for angle metrology, it can be used for testing universal Bevel Protractors and angle templates and can be composed with auxiliaries for testing the internal, external angles of parts and adjusting the angle on machine center. The Angle Gage Blocks divides as type I (with one working angles) and type II (with four working angles).The deviation of the working angles for 0 grade is not over ± 3 seconds, the deviation of the working angles for 1 grade not over ± 10 seconds and the deviation of the working angles not over ± 30 seconds.When order , please indicate name,set number and precision grade.For example :Angle Gage Blocks 7 Pieces 0 grade.
